12 volt battery question
A buddy of mine is upgrading a backup power source at his job and he replacing about 100 12volt deep cycle batteries, some of which are only a couple of months old. My question is can I use 8 12volt batteries rigging 2 in parrallel making 4 sources of 12 volts totaling 48volts? They are gell cell batteries an I really hate for them to go to waste. I have an 01 EZ-GO with a 502-1 motor and a alltrax controller. It's rigged for 36 volts, but I was planning to go to 48 volts anyway
Any help would be greatly appreciated. |

Re: 12 volt battery question
Wow..I would love to have access to batteries like that !! In theory yes. What is the amp hour rating on the batteries ? Why not go to 72v or 96v if ya gonna upgrade. My next project is gonna be that..as soon as the wife lets me get anther project car :-). Check over or post over at extreme DC thread. chances are someone has done something like you want.

Re: 12 volt battery question
I have a setup that can go up to 48 volt. I know I will have to upgrade my charger. Will a 48 volt charger work on that system?

Re: 12 volt battery question
If you go forward with this a common golf cart charger is not correct for that battery type.

I did a quick search and found this. I am sure there are others. Just search. Sounds like a fun project. joe |

Re: 12 volt battery question
I have a 36 volt charger for my current system. Just out of curiosity... If I sell it, what should I ask for it? It's a power wiz charger that came with my ezgo cart

Re: 12 volt battery question
Before you start shopping for an appropriate charger, post some specs on these free batteries. They may be totally inappropriate for a cart.

Re: 12 volt battery question
The batteries are out of a UPS system. They are the correct size. They are Gell Cell 400 amp batteries. That's all I know. Is there anything else I should check on?
